contributions” 1. Isaac Newton quantified and qualified the laws of motion and gravity. He also invented the reflecting telescope and co-invented the mathematic process of calculus. 2. Albert Einstein developed theories of relativity‚ and won a Nobel Prize for his work on the photoelectric effect. 3. Galileo Galilei improved on the refracting telescope and discovered the four largest moons of Jupiter‚ but he is most well-known for standing up for Copernican theories of a heliocentric

Galileo used physics (Dialogue Concerning the Two Chief World Systems) to support Copernicus’ Heliocentric theory. Kepler mathematics (laws of planetary motion) and his expertise in optics (inventing an improved version of the refracting telescope (Keplerian Telescope) and gave credit to Galileo for his telescopic discoveries) to support the Heliocentric model. The Heliocentric model was accepted as the structure of the Solar System because of the work of these ancient scientists and the

Sir Isaac newton had a gigantic effect on society and even now teachers are still teaching his three laws of motion from 1687. He has published the most revered book in science known as Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) which is more commonly known as Principia. He helped explain elliptical planetary orbits and nearly every motion in the universe including how all of the planets in our solar system revolve around the sun. Isaac Newton

like in 1010. The first event that I attended was the courtyard telescope setup on January 31st‚ in which we were observing a couple of different provinces and sunspots located about 10 o’clock region located directly on the sun. (See lab book for illustration.) We were experiencing “H-Alpha Light” which is a type of light that is not emitted as much from the sun. We used a hydrogen-emission lens used on a simple refracting telescope. The second event that I went to was an observing done by Dr

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Telescope... A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. They found use in terrestrial applications and astronomy.Within a few decades‚ the reflecting telescope was invented‚ which used mirrors. In the 20th century many new types of telescopes were invented

Galileo Galilei‚ born Febuary 15th 1564 and died January 8th 1642‚ was a major contrubitor to science during the Scientific Revolution. As a physicist‚ mathematician‚ astronomer‚ and philosopher‚ his contributions include improvements to the telescope and consequent astronomical observations and support for heliocentrism. He also conducted experiments with pendulums‚ establishing the relationships between length and period. He also applied these principles to gravity‚ determining that objects

when the sun is the put at the center of the universe and the planets revolve around the sun. Proposed by: Nicholas Copernicus Why this belief was proposed: A little less than 100 years later‚ a new generation of scientist with the help of the telescope‚ confirmed Copernicus’s theory. A German mathematician‚ John Kepler‚ came up with the next solution to the puzzle to predict planetary motion accurately. His observations led to astronomers realizing that planets orbit the sun in elliptical paths

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.
